DOOR-HANGER TRACK.

SPECIFICATION forming part of Letters Patent No. 617,027, dated January 3, 1899'. Application filed February 25, 1898. Serial No. 671,707. (No model.)

To a/ZZ whom it may concern:

Be it known that I, LEWIS A. KIRK, a citizen of the United States, residing at Valparaiso, county of Porter, and State of Indiana, have invented a new and useful Door-Hanger Track, of which the following is a specification.

My invention relates to an improvement in door-hanger tracks, with the object in View of providing a light, durable, and comparatively inexpensive track for supporting and housing the door-sustaining rollers.

My invention further relates to the means for utilizing either a single track or a double track at pleasure and at the same time provide against the door crowding the wall or building at the bottom whether the track be double or single.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a partial view of a door and the mechanism for hanging it in front elevation. Fig. 2 is a vertical section on the line 2 2 of Fig. l, and Fig. 3 is a similar section showing a single track and roller instead of a double track and rollers.

The track, which at the same time forms a cover, is denoted by T and extends horizontally along the distance which it is intended the door shall travel to and from its closed position. The track consists of a continuous strip of metal, which may be conveniently sheet metal and may be formed in the desired shape by suitable dies. In the present instance it is provided at its top with a portion t, adapted to rest at against the face of the building or against the upper portion of an interposed sheet of metal for forming an inner track when a double track is used, and is curved over the top of the inner sheet, (shown at t',) so as to make a tight joint with the face of the building to prevent the entrance of water into the track. Below the portion the track T slants downwardly and outwardly, as shown at t2, thence downwardly, as shown at t3, and thence curves inwardly and upwardly, as shown at t4, forming a curved track, in the bight of which the antifriction-rollers supporting the door are intended to travel.

The track C so constructed is held firmly in position by means of stili. brackets or hangers B, shaped to conform to the track T throughout the portions t, t2, and t3, the part b of the hanger being curved over toward the face of the building to conform to the part t' of the track and form a tight joint against the face of the building', while the parts b, b2, and b3 rest snugly against the outer faces of the portions t, 252, and t3 of the track. Bolts G, extending through the portions b and t of the hanger and track and into the building, lock the parts firmly in position. The track T may be further secured to the hangers B by fasteners R, extending at suitable intervals through the parts h3 and 3 of the hanger and track, respectively.

When a single track is employed, as in the form represented in Fig. 3, the space next to the face of the building and opposite the bight t4 of the track may be filled by a strip of wood P, fastened to the face of the building and extending the full length of the track, so as to make the aperture between the exterior and the space inclosed by the track T as narrow as consistent with a free working of the door. In the form represented in Fig. 2 the strip of wood P is replaced by a second track T', consisting, like the track T, of a sheet of metal curved outwardly and upwardly at its lower end, as shown at t5, to make a concave track like f1. This may be fastened to the building near its lower end by a series of screws k, and when used the door may be supported by a pair of antifriction-rollers W W instead of a single antifriction-roller W, as in the form shown in Fig. 3.

The hanger H, which connects the door D with the axle of the antifriction-rollers, has located within its head a series of cylindrical rollers e, located between the axle N of the antifriction-rollers and the interior wall of the head of the hanger, so as to eifectually prevent friction. The axle N may be fixed to rotate with the rollers, the rolling friction being taken by the axle N and the antifriction-rollers e.

The structure as a whole is simple and durable and may be readily set up by unskilled as well as skilled labor, and the conversion IOO from a single track to a double track, or the opposite, may be readily accomplished to suit the demands by simply having on hand the double suspension-rollers and the additional track F.

What I claim is- 1. A door-hanger track consisting of a continuous strip of sheet metal curved inwardly and upwardly at its lower end to forrn a seat for suspension-rollers and extending inwardly and upwardly along its upper edge to form a cover for the suspension-rollers and their seat and for securing it to the building, the inner side of the said curved sheet-metal track being open to admit the suspension-rollers into their seats, supporting-brackets made to con` form to the exterior shape of the track for supporting the track, fastening devices adapted for use in connection with the brackets and track for holding them irmly in position, and means intermediate of the said track and the building for holding the supporting-roller and the door carried thereby against displacement, substantially as set forth.

2. The combination with a track consisting of a sheet of metal turned at its lower edge inwardly and upwardly to form a concave seat for the suspension-roller and extending at its upper edge inwardly and upwardly to form a cover for the suspension-roller and its seat and brackets for removably securing the track in its position, the inner side of the said track being open for the reception of the suspension-rollers, of an inner track consisting of a sheet of metal constructed to rest flatly against its support and curved outwardly and upwardly at its lower end to form a concave seat for the reception of a suspension-roller and means for securing the said inner track to its support, substantially as set forth.
